Particle separation apparatus

Abstract

A particle separation apparatus includes: a liquid supply unit A; a liquid supply unit B; and a control unit. The liquid supply unit A produces a mixed liquid by mixing the liquid A and a liquid C, and supplies the liquid A to the separation device as the mixed liquid. The control unit controls the liquid supply unit A and the liquid supply unit B to supply the liquid B from the liquid supply unit B to the separation device so as to fill the separation device with the liquid B while producing the mixed liquid by the liquid supply unit A, and supply the liquid A from the liquid supply unit A to the separation device as the mixed liquid after the separation device is filled with the liquid B.

What is claimed is: 
     
         1 . A particle separation apparatus that separates a particle from a liquid A including the particle by using a separation device configured to separate the particle from the liquid A, the particle separation apparatus comprising:
 a liquid supply unit A that supplies the liquid A to the separation device;   a liquid supply unit B that supplies a liquid B to the separation device; and   a control unit that controls the liquid supply unit A and the liquid supply unit B, wherein   the liquid supply unit A produces a mixed liquid by mixing the liquid A and a liquid C, and supplies the liquid A to the separation device as the mixed liquid, and   the control unit controls the liquid supply unit A and the liquid supply unit B to
 supply the liquid B from the liquid supply unit B to the separation device so as to fill the separation device with the liquid B while producing the mixed liquid by the liquid supply unit A, and 
 supply the liquid A from the liquid supply unit A to the separation device as the mixed liquid after the separation device is filled with the liquid B. 
   
     
     
         2 . The particle separation apparatus according to  claim 1 , wherein the control unit performs control to connect the liquid supply unit A to the separation device while supplying the liquid B from the liquid supply unit B to the separation device so as to fill the separation device with the liquid B. 
     
     
         3 . The particle separation apparatus according to  claim 1 , wherein the control unit performs control to connect the liquid supply unit B to the separation device while producing the mixed liquid by the liquid supply unit A. 
     
     
         4 . The particle separation apparatus according to  claim 1 , wherein
 the liquid supply unit B is configured to send out a cleaning liquid, and   the control unit performs control to send out the cleaning liquid from the liquid supply unit B with the liquid supply unit B being detached from the separation device.
